CER0109B

Ceramic filters are electronic components which are widely used in radio frequency (RF) and microwave communication systems. The CER0109B also fits into this category and is used in cellular base station and repeaters for frequency planning, harmonic filtering as well as signal receiving. This device offers excellent performance characteristics including low insertion loss and wide passband, very low temperature coefficient, good isolation. It is suitable for usage in a wide variety of applications such as mobile communication, CDMA/GSM/WCDMA, satellite, FM, etc. The CER0109B is a ceramic filter with a wide range of applications.

The CER0109B has two main parts, the first one is the resonator and the second one is the resonator holder. The resonator is a strip-shaped monolithic component which contains multiple parts such as capacitors, inductors and resistors that perform the filtering functions. This component is designed to remove unwanted signals from the incoming signal. The resonator holder holds the resonator and provides electrical connection between the resonator and the external circuit. The holder is also designed to guide the resonator at the correct position so that the specified frequency response is achieved.

The working principle of the CER0109B is quite simple. When an electrical signal is applied to the resonator, it transmits energy at a certain frequency depending on the components used within the ceramic filter. This energy is then filtered out from the incoming signal and the signal of specific frequency is produced. The CER0109B also allows you to adjust the frequency response of the filter by changing the components within the ceramic filter. This is done by exchanging capacitors, inductors and resistors with different values.

In conclusion, the CER0109B is a ceramic filter designed for applications in radio frequency and microwave communication systems. It offers excellent performance characteristics and has a wide range of applications. The working principle of the component is quite simple and can easily be adjusted by changing the components within the ceramic filter.
